Cricetulus griseus (Chinese hamster)

, 1967
The long arm of the X may show a weak secondary constriction at the distal third. However, without autoradiography with tritiated thymidine, the X may be indistinguishable from chromosomes No. 4. The Y chromosome is morphologically unique.

A comparative analysis of the karyotypes of Cricetus cricetus and Cricetulus griseus

Chromosoma, 1976
This study presents a comparison of the mitotic chromosomes of the two species of hamsters Cricetus cricetus (European hamster) and Cricetulus griseus (Chinese hamster), which have the same chromosome number of 2n=22.--G-banding procedure reveals striking similarities in both karyotypes and gives the possibility to analyse structural changes so that ...

Circadian variations in pinealocytes of the Chinese hamster, Cricetulus griseus

Cell and Tissue Research, 1983
Circadian morphological variations of pinealocytes in the superficial pineal of the Chinese hamster (Cricetulus griseus) were studied using quantitative electron-microscopic techniques. The volume of the nucleus and cytoplasm of pinealocytes exhibited similar circadian variations, with the maximum around the middle of the light period and the minimum ...

Ultrastructural observations on the pineal gland of the Chinese hamster, Cricetulus griseus

Cell and Tissue Research, 1982
The ultrastructure of the pineal parenchymal cells, pinealocytes and glia-like cells, of the Chinese hamster (Cricetulus griseus) is described. Pinealocyte nuclei contain spindle-shaped inclusions consisting of bundles of closely packed parallel filaments of about 8 nm in thickness. Mitochondria contain lamellar and tubular cristae.

Sozialsystem adulter chinesischer Zwerghamster (Cricetulus griseus)

Zeitschrift für Tierpsychologie, 1977
AbstractThe social system of 4 adult Chinese hamsters was analysed under semi‐natural conditions in a large enclosure. In all trials the home ranges overlapped, but were patterned in a different way and patrolled in turn. ♂♂ were inferior and less aggressive than ♀♀ and had to change their nest site more frequently.

Effect of Circadian Rhythm on the Radiation Response of the Chinese Hamster (Cricetulus griseus)

Radiation Research, 1972
More than 1000 Chinese hamsters, 80 days old, were used to examine the radiation response of Cricetulus griseus at different times during a 24 hour day. The ${\rm LD}_{50/30}$ values were calculated to be 954 rads (1 AM), 889 rads (9 AM), 823 rads (11 AM), 886 rads (1 PM), and 882 rads (3 PM).

Blastocyst implantation in the chinese hamster (Cricetulus griseus)

American Journal of Anatomy, 1990
AbstractEmbryonic development of the Chinese hamster (Cricetulus griseus) was studied from the onset of implantation to the formation of the parietal yolk sac placenta. Implantation began on day 6 of pregnancy, when the embryo became fixed to the uterine luminal epithelium. At this time there was no zona pellucida, and microvilli of the trophoblast and

Stages in the prenatal development of the Chinese hamster (Cricetulus griseus)

Anatomy and Embryology, 1979
A system of staging embryos is described for the Chinese hamster (Cricetulus griseus). This system of staging, based on Streeter's developmental horizons in human embryos, comprises three sets of criteria: 1) data on postconceptional age, size and number of somites, 2) external characteristics and 3) internal characteristics. A comparison has been made
